DX12 Rise of the Tomb Raider on Nvidia - Bugged on Ryzen?

His conclusion is more like it seems NVidia's DX12 Drivers don't work as well as AMD's.

Right, Nvidia's DX12 drivers seem broken when paired with Ryzen.

Here someone tested Division DX11 vs DX12 with 470 and 1060 3GB:

Same thing, DX12 was way slower on Ryzen for Nvidia, and faster on AMD.

Wonder if having to do async compute and other things driver side instead of hardware is the problem? Wonder if someone can test forcing async compute off through the registry for ROTTR and see if it changes the performance at all.

I would imagine that AMD's drivers would work better with Ryzen considering that AMD has had the kind of information they would need to make sure it performs well, whereas NVidia wasn't going to get early information.

Considering AMD didn't have a worthwhile CPU for ~5 years, I wouldn't be surprised if NVidia's drivers specifically target Intel CPUs without considering that something else might exist, and that making assumptions about the CPU could cause performance loss if those assumptions don't hold.

I doubt that it's anything particularly sinister on NVidia's part. Why spend a lot of effort on AMD CPUs when so few people were buying them. With Ryzen looking more and more competitive after updates, I think NVidia will come around to fixing any problems or it would mean that if you have a Ryzen CPU you almost have to get an AMD GPU as well and that's lost sales.

It was known even before DX12 released, that Nvidia will have higher CPU overhead this time around. And it was visible in many games for the past year. In some games the difference is small, but shows very clearly now with Ryzen. I want to see the same test done in Hitman DX12, as it is one of the biggest outliers in Ryzen game tests.

Drivers can optimize at the CPU side so it's not a surprise that Nvidia isn't upto par when running with Ryzen since it's a relatively new microarchitecture ...

Plus they have a stake in stopping AMD from reaching gaming performance parity with Intel as more revenue with higher profits means a stronger graphics division for AMD in the end ...

 

[Elixer]

Yeah, I am sure nvidia's drivers can be tuned to run better on Ryzen, as well as most everything else.
This is what happens when you go so long without a good, competitive product, and now, everyone must play catch up.
I wouldn't be shocked to see other drivers ( & other software) have the same kind of issues as well.

 

[SPBHM]

it looks to be case, since this behavior is not happening in other games it's probably something that can be patched.

still very interesting that this was overlooked by so many, simply because no one is testing CPUs with AMD cards anymore.

 

[Bacon1]

Looks like its more than just ROTTR

Having worked with a Ryzen 1800x and 3 mbs so far ( Asus Prime B350 Plus, MSI X370 XPOWER Titanium and Asus ROG Crosshair VI) in combo with 2 Sapphire RX480 reference cards in CF, AMD is being pulled all ways right now just to get the BIOS tweaks to the MB vendors. Though the RGB division is under the AMD umbrella, I bet they don't have much more info for tweaking for Ryzen based cpus since the CPU division has to get the info to the MB manufacturers first.

Not a perfect analogy, but when the RX480 came out it really had "teething" pains at first. AMD cpu division stepped up to the plate on the power issue and corrected that quickly. Video drivers have slowly but surely been improving.

I have a "hunch" that at RGB division, it's "all hands on deck" time to get Vega launched. Tweaking for DX12 Rise of Tomb Raider might be on the radar screen for the AMD Radeon division but just not near the top of the list.

P.S. Ryzen is clearly in it's infancy and I suspect Nvidia wants to wait until the microcode tweaks released to the mb manufacturers in the coming months for Ryzen chipsets is implemented.

What do you think AMD needs to do with DX12 ROTTR? It's clear that the issue resides with Nvidia's drivers not Ryzen / AMD GPUs.

The issue seems to be more with CPUs with more than 4 cores rather than Ryzen in particular. The Intel 8 core CPUs are similarly affected.

Nvidia have done a lot of work over the years for multi-threaded DX11 performance and with Intel artificially separating the 6-8 core CPUs from the average gamer by pricing them out, all the focus as been on 4c/4t since the high IPC i5 was basically the staple.

Now that AMD is turning the market upside down and introducing high core CPUs available at accessible prices, these issues are coming to light.

At least that's my take on this whole situation.

This guy (RedGamingTech), updated his MSI BIOS (Titanium,to 1.3) and received a significant boost in ROTTR. He said from 90FPS, to over 115 FPS. Nothing else had changed.

So, it may not be drivers at all.

Digitalfoundrys benchmark shows that Nvidia's DX12 works just fine with I7-6900k, it's actually faster than I7-7700k in RotR:

4:04 RotR.

So the problem seems to be mostly with Ryzen.

Except the test done in the same bios for both DX12 in AMD and DX12 in Nvidia and AMD works fine.

So the problem seems to be mostly with Ryzen.

Nvidia's DX12 driver and Ryzen

It looks like its all dx12 games with ryzen not only tomb raider.

Nvidia's DX12 driver and Ryzen

Yes, though I wouldn't be suprised if their DX11 driver overhead on Ryzen would be bigger than Intel counterparts, afterall their code is heavily optimised for Intel. And it's very likely that AMD will also still find extra efficiency. You don't tune 100% efficiency in few months.

 

[Bacon1]

Looks like BF1 is bugged as well: 470 and 1060 3gb DX11 vs DX12:

All dx12 games with nv gpu.

And not only Ryzen, FX series also. Just poor cpu performance in general. And it's visible on Intel cpus also. There is just not enough tests online, and no high end AMD gpus to show it more clearly.
